Voltage Pulses Can Flip, Create, and Erase Magnetic Bimerons in Two-Dimensional Ferroelectrics
Researchers have demonstrated that voltage pulses can write, erase, and invert magnetic bimerons in a two‑dimensional ferroelectric by flipping the material's polarization. The flip reverses the Dzyaloshinskii‑Moriya interaction (DMI) chirality, changing the bimeron's topological charge from +1 to ‑1, while an antiferroelectric phase nullifies DMI and removes the bimeron entirely. Using density‑functional theory and atomistic spin simulations on monolayer CuV₂I₆, the team quantified exchange, DMI, and anisotropy parameters, showing stable bimerons at 105 K and a 116 meV energy barrier between ferroelectric states. The work proposes a purely electric‑field route to control topological spin textures without current flow.
Upcoming US Clinical Trial to Test a Tiny Eye Implant that Could Restore Sight for Age-Related Macular Degeneration (AMD)
USC’s Roski Eye Institute, together with Regenerative Patch Technologies, is launching a phase 2b, multicenter, masked clinical trial of a stem‑cell‑derived retinal pigment epithelium (RPE) implant for advanced dry age‑related macular degeneration (AMD). The ultra‑thin patch, derived from embryonic stem...
Relief From Tooth Sensitivity with Magnetically Guided Nanobots
Researchers at IISc and deep‑tech startup Theranautilus have engineered CalBots, magnetic nanobots that penetrate dentinal tubules and form durable bioceramic seals to alleviate tooth hypersensitivity. The 400‑nm particles are guided by an external magnetic field, reaching depths of 300‑500 µm and...
A Bioinspired Hydrogel Patch with Controllable Adhesion Properties for Enhanced Soft Tissue Repair
Researchers from Shenzhen University, the Chinese Academy of Sciences and Hong Kong Polytechnic University have created a bioinspired hydrogel patch with controllable adhesion for soft tissue repair. The dual‑sided device combines a suction‑cup‑like adhesive layer that can be repositioned and...
Healing Brain Cells and Tackling Neurodegenerative Diseases with Nanoflowers
Researchers at Texas A&M have shown that metallic “nanoflower” nanoparticles can protect and repair brain cells by improving mitochondrial health. In cell cultures, the nanoflowers sharply lowered reactive oxygen species and enhanced mitochondrial integrity within a day, and in C....
